• Thanks to the independence of the door system, SIDOOR is highly exible and can be easily 
expanded with modular communication interfaces. SIDOOR door controllers can be 
completely controlled by a SIMATIC S7 controller. Control, parameterization and diagnostics 
takes place via PROFIBUS or PROFINET.
• The system's reliability, ruggedness and long-term precision minimize the need for 
maintenance and repair work. Obstruction and belt tear detection provides more safety.
